Improvement in photographic albums



UNITED STATES PATENT OFFICE.

RICHARD VAN VELTHOVEN AND JOSEPH H. HAZZAR-D, OF PHILADELPHIA,PENNSYLVANIA IMPROVEMENT IN PHOTOGRAPHIC ALBUMS.

Specification forming part of Letters Patent No. 50,521, dated October17, 1865.

To all whom it may concern:

Be it known that we, R. VAN VELTHovEN and J. H. HAZZARD, ot'Philadelphia, Pennsylvania, have invented an Improvement in PhotographicAlbums and other Books; and we do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, and to the letters of reference markedthereon.

Our invention consists in certain iiexible strips formed and combinedwith the leaves ofv an album or other book, substantially as describedhereinafter, so that the said leaves shall be firmly bound together.

In order to enable others skilled in the art to apply our invention, wewill now proceed to describe the manner of carrying it into effect.

On reference to the accompanying drawings, which forni apart of lthisspecitication, Figure l represents a number of leaves of a photographicalbum secured together according to our improvement; Fig. 2, a sectionon theline l 2, Fig. 1; Fig. 3, a section 011 the line 3 4, Fig. l, Fig.4, a view, looking at the back of the book, Fig. 5, an edge view of partof the book; Fig. 6, view representing two of the leaves disconnectedfrom each other; Fig. 7, aview showing the manner in which the stripsfor securing the leaves together are combined, and Fig. 8 one of thestrips.

Similar letters refer to similar parts throughout the several views.

A, A', A2, B, B', and B2 are leaves of a photographic album, and to theinner edges of each ofthe leaves A, A', and A3 on one side of thesame,is pasted or otherwise secured astrip, O, of parchment or othermaterial, a portion of this strip projecting beyond the edge of theleaf, passing across the inner edge of the adjacent leaf, B, B', or B2,and being pasted to the opposite side of the next leaf, A, A', or A2, asbest shown in Fig. 2.

Each strip O may be divided into three parts, c, c' and c". The portionc, from one edge of the line y, Fig. 8, is secured to the edge of oneleaf, A, the -portion c', between the line y' and the opposite edge ofthe strip is secured to the edge of another leaf, and the central vportion, c", between the lines y y', passes across the edge of theintermediate leaf, as above described. j

In the center of the strip O, between the lines y y', are a number ofslots, c a, and the portion c' of the strip is cut along the lines a?,so as to form a number of T-shaped tongues or projections, b, which areconnected with the plain portion c of the strip onlyT by the necks c,which are equal in length to the slots or openings a. The leaves B,B',and B2 are connected together in a similar manner by somewhat similarstrips, O', the form ot' Which is best shown in Fig. o'. It will beseen, however, that While the tongues b at each end of the strips O areincomplete, heilig, in fact, of an L shape, as shown in Figs. 6 and S,the tongues b in the strips C' are all perfect, the two strips being' soformed that when placed side by side, as shown in Fig. 6, the necks e ofthe tongues in one strip will be opposite the the slots a in the otherstrip.

When a number ot' leaves are to be bound together the leaves A, A', andA2 are connected to each other in the manner described, and as shown inFig. 2. The portion c of one of the strips O' is then secured to oneedge of the leafB, Fig. 2, and the latter is introduced between theleaves A and A', the tongues b of the strip O' being so folded up thateach may pass readily through 011e of the openings a. in the strip O,secured to the leaves A and A', and also through the openings a in thestrip O, (marked O21.) secured to the leaves A' and A2. The ends of thetongues b, which project beyond the strip O2, and which form the portionc' of the strip C', are then unfolded and pasted to the side of a leaf,B', which is introduced between the leaves A' and A2. To the oppositeside of the leaf B' is secured another strip, C', and the tongues b,projecting from the edge of this strip, are then passed through theopenings a in the strips O, (marked O2 and 03,) secured to the leaves A'and A2, and the portions of these tongues projecting through the stripC2 are secured to the side of the next leaf, B2,

additionalleaves bcingsecuredin asimilarmanner to those thus boundtogether until a book of the size required is made. By this means theleaves are bound so firmly together that the edges of the same alwayscoincide, the

leaves being prevented from sliding across each other, as is the casewhen heavy boards or leaves are bound together in the usual inanner.While the leaves are thus firmly bound together they will open readily,and when opened will lie perfectly lat, without that tendency of thecentral leaves to assume an upright position, which is so usual andobjectionable in books bound in the ordinary manner.

Although We have only referred to the leaves of photographic albums asbeing bound in this manner, it will be apparent that this invenl tionmay be used in securing together the heavy boards of which books areformed for exhibiting patterns of fabrics, and for other similarpurposes.

Without coniining ourselves to the precise forni herein described of thestrips C C', or to RICHARD VAN VELTHOVEN. JOSEPH H. HAZZARD.
